MQ-138 MQ138 Semiconductor Gas Sensor For Domestic VOC Gas Alarms
|
...Gas Sensor For Domestic VOC Gas Alarms Working Principle: The SnO₂ sensitive material of the MQ138 gas sensor has low conductivity in clean air. When volatile organic compounds (VOCs) or other target gases are present, the sensor's conductivity increases with the rise of the gas concentration. Users can convert the change of conductivity into a corresponding output signal of gas......
